Given numbers are 557, 812, 398, 403

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(557, 812) = 452284

GCD(557, 812) = ( 557 x 812 ) / 452284

= 557 / 812

= 557

Step2:

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

= 1 / 398

= 1

Step3:

LCM(1, 403) = 403

GCD(1, 403) = ( 1 x 403 ) / 403

= 1 / 403

= 1

So, Greatest Common Divisor of 557, 812, 398, 403 is 1
